Jakarta. Siloam Asri Hospital in Pancoran, South Jakarta, has taken preemptive measures after Dharmais Hospital in the west of the capital fell victim to a massive global cyber-attack over the weekend.
The "WannaCry" ransomware locked data on at least 400 computers at Dharmais Hospital, with popup messages displayed on screens stating that access to the data will only be restored after payment of $300, or about Rp 4 million.
To protect its computer network, Siloam temporarily disconnected internet connections on Sunday evening (14/05), after backing up all patients' data.
The hospital was not affected by the malicious software.
"We have coordinated with the IT teams of all Siloam hospitals to prevent [the cyber-attack]. We have shut down all internet access, backed up data, and updated our software and antivirus [programs]," Agus Cepi Cahyadi, head of Siloam Asri Hospital's information technology division, said on Monday.
Reuters reported that cyber-extortionists tricked victims into opening malicious malware attached to spam e-mails.
The Ministry of Communication and Information Technology has called on companies to update their security software before connecting their computers to local area networks on Monday.
The Jakarta Globe and Siloam Hospitals are both affiliated with the Lippo Group.
